An example system may include a housing and a planetary gearbox disposed within the housing, wherein a ring gear of the planetary gearbox is coupled to the housing, a sun gear of the planetary gearbox is coupled to a drive shaft, and a planetary carrier of the planetary gearbox is coupled to an output shaft.

Abstract: An openhole interval of a well may be sealed by deploying a liquified phase transformation material to the openhole interval and allowing it to harden. In at least one example, this may be performed in a single step of building and maintaining pressure. The pressure may rupture a membrane, to introduce a fluid into a chamber with a reactive material (e.g. powder) in a delivery chassis, whereupon the fluid may exothermically combine with the reactive material to liquify the solid phase transformation material. The same applied pressure may also deliver the liquified phase transformation material to a deployment chassis, which then distributes the liquified phase transformation material under pressure to the openhole interval of the well. Various delivery chassis, deployment chassis, and related compositions and methods are disclosed as well.

The packer assembly is coupled to the tool body and creates a fluid barrier in the annulus formed between the tubing string and the wellbore.

Abstract: A rotary latch release mechanism includes axially-aligned upper and lower rotary latch components carried on and rotationally coupled to upper and lower latch assemblies, respectively. The latch release mechanism is movable from an axially-latched position to an axially-unlatched position in response to relative rotation between the upper and lower rotary latch components. The latch release mechanism has a movable land surface that acts in response to relative axial displacement to induce the relative rotation required to release the latch. The latch release mechanism may be configured such that the axial movement of the movable land surface will cause the relative axial movement required to release the latch in combination with the required rotation. Accordingly, the rotary latch mechanism operates in response to externally-controlled axial movement of a movable land surface carried by the latch release mechanism, without requiring externally-induced rotation.
